• Contraluz opals are very rare. They are usually found in Mexico but have also been found in Australia. They are transparent opals and show a play of color in both transmitted and reflected light. - Taken from gemsociety.org

THIS OPAL IS SOMETHING TRULY SPECTACULAR. FIRSTLY IT IS A CRYSTAL OPAL WHICH ARE ALWAYS TRANSPARENT. THAT IS WHY THE PICTURE IS SO LIGHT. SECONDLY IT IS A CONTRA-LUZ OPAL. CONTRA-LUZ IS THE NAME USED FOR COLOUR-PLAY THAT THAT IS VISIBLE WHEN THE LIGHT IS BEHIND THE OPAL. THIS EFFECT ONLY OCCURS IN STONES THAT ARE TRANSPARENT OR NEARLY TRANSPARENT.

PLEASE NOTE THAT THESE ARE NOT PICTURES OF THIS OPAL. THEY ARE MERELY TO SHOW THE CONTRA-LUZ EFFECT. 

THIS OPAL HAS A BEAUTIFUL RAINBOW THAT COLOUR-PLAYS WHEN YOU PUT THE TORCH BEHIND IT, OR WHEN YOU LAY IT ON THE TORCH. DO NOT MISS OUT ON THIS STUNNING PINK CONTRA-LUZ RAINBOW OPAL

BIT OF INTERESTING OPAL TRIVIA. DID YOU KNOW, THAT IF AN OPAL IS NOT MANAGING TO FIRE OR FLASH EN CABOCHON, THEY WILL THEN FACET THE GEMSTONE TO GET IT FIRE.
